Hi building my first pc and already got the nzxt h7 flow 2024 and was wondering what to do about fans, it comes with 3 120mm fans but they are 3 pin ones so thinking about replacing them, according to the specs i can have :

top 3x120mm or 2x140mm.
1 rear 120mm or 140mm.
3 front 120mm or 140mm.
3 bottom 120mm.

thinking 3 bottom 120mm,1 rear 140mm,3 front 140mm and 1 or 2 top 140mm.
any advice.
priority is quiet so will probably run them at low speeds.
don't want to spend a fortune.
will probably spend more on the 1 rear fan than the other fans individually.
